LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 441,295, dated November 25, 1890.

Application led April 4, 1890. Serial No. 346,527. (No model.)

To all whom t may concern.-

Be it known that I, ABRAM D. EMERY, of Taunton, Massachusetts, have invented cer-` tain Improvements in Loom-Shuttles, of which the following is a specification. I This invention relates to iiy-shuttles used in Weaving; and it consists in reducing the size of such shuttles by diminishing the area of their transverse section, whereby a smaller opening or shedding of the Warp-threads becomes permissible, and also in conforming the shape of the shuttle in transverse section to the shape of the cop in transverse section, thus eiecting an approximately-uniform distribution of lthe material of which the shuttle is made and increasing the accuracy With Which the shuttle can be thrown or driven in the process of Weaving. These objects are accomplished by constructing the shuttle in the form of a cylindrical shell having spindling or conoidal ends, one of which is detachable to permit the introduction of the cop into the cylindrical portion of the shuttle, which portion constitutes the cop-chamber. At or near one end the shuttle is provided with a guide-tube to serve as a leader for the thread or yarn as it is unWound from the cop in the act of Weaving.

- Shuttles embodying the invention may be made of light sheet metal or of Wood or any other suitable material or materials.

l The detachable end of the shuttle may be provided with an ordinary cop spindle or skewer, or with a pin for insertion in the head of a bobbin upon which the cop has been wound, in either of which cases the opposite end of the shuttle will be provided With the guide-tube or leader and the shell of the cylinder Will be preferably provided with a slotted opening to facilitate threading the cop thread or yarn .through the leader, or the detachable end of the shuttle may be provided with the guide-tube or leader When the `copchamber is to be occupied by a copwhich un- Winds from the inside and is inclosed in a rough surface-covering, as described in another application, led March 27, 1890, and having Serial No. 345,486.

The accompanying drawings, illustrating 1shuttles containing the invention, are as folows:

Figure 1 is a central longitudinal section of the improved cylindrical shuttle adapted for holding a cop of the kind which unwinds from the inside, and Which is surrounded With a wrapper or casing preparatory to its introduction into the cop-chamber. Fig. 2 is a central longitudinal section of the improved shuttle, the detachable end of which is provided with a skeWer for insertion through a cop of the kind whichv unwinds from the outside in the process of Weaving. Fig. 3 is a central longitudinal section of a shuttle containing the invention, the detachable end of which is provided With a pin adapted for insertion in the head ot a bobbin upon which the cop is Wound. Fig. 4 is a cross-section of the cylindrical shell A, taken through the plane indicated by the line X X on Fig. 1. Fig. 5 is a cross-section of the cylindrical shell-A, taken through the plane indicated by the dotted line y y on Fig. 3. Fig. 6 is a cross-section of the detachable end and bobbin, taken through the plane indicated by the dotted line Z Z on Fig. 3. Fig. 7 is side view of the shuttle.

S is a longitudinal section of the detachable end and the adjacent portion of the cylindrical shell shown in Fig. 3, representing them as detached from each other. Fig. 9 is a longitudinal section of a cop Wound upon a bobbin, the head of Which is provided with solid steady pins or lugs. Fig. 10 is a longitudinal section of a portion of the cylindrical shell A, provided with a solid conoidal end, and of its detachable end, also made solid. Fig. l1 is a longitudinal section of the end portions of a shuttle provided With more or less elastic filling. Figs. 12 and 13 are crosssections illustrating methods of providing the shuttle with external proj ections by means of longitudinal corrugations.

The shuttles represented in the drawings are alike in respect of the fact that in each of them the cop is contained Within a cylindrical shell A, provided with spindling or conoidal ends A and B, one of Which endsas, for example, B-is made detachable for the purpose of allowing access to the copchalnber C for the introduction of the cop D.

The detachable end B of the shuttle maybe telescopically jointed to the end of the cylinder A, as indicated in Fig. 1, or the meeting end of the cylinder A and of the detachable end B may each be provided With a series 0f IOO equidistant outwardly-projecting tongues, as shown most clearly in Fig. S.

The tongues a a a. d of the cylinder A are adapted to enter the detachable end B in the spaces between the tongues b b l) b, and the tongues b l) b b are adapt-ed to enter the cylinder A in thespaces between the tongues a a L a. The tongues are thus i nterplaced, and their frictional bearing upon the interior surface of the cylinder A and detachable end B, respectively, operate like a telescopic joint to hold the parts together; but for additional security the detachable end B may have afixed to it the spring-catch E, Figs. 1 and 2, in such position that the tooth e of the catch will spring outward into the hole e', formed through the cylindrical shell A, in which case the separation of the detachable end B from the cylindrical shell A is effected by such inward pressure upon the tooth ,e as will suiiice to clear it from the side shell and permit the end B to be pulled out. The spring-catch may, if desired, be also used to supplement the telescopic joint, as shown in Fig. 1.

'In Fig. 1 the shuttle is represented as .adapted to receive a cop of the kind which unwinds from the inside in the act of Weaving and which is inclosed in a rough surfaced covering prior to its introduction into the copchamber. The said covering may be in the form of a hinged metallic tube, or it may consist of awrapper of iiexible material, such as emery-cloth or sand-paper, as described in pending application, Serial No. 845,486, filed March 27, 1890. The cop thread or yarn is led outward through the guide-tube or leader F, which may be afiixed to the detachable end B, as represented in Fig. 1, when the shuttle A is to be employed for carrying cops of the kind which unwindvfrom the inside, or it may be affixed to the end A of the shuttle, as represented in Figs. 2and 3, in which latter case the shell A will preferably be provided with one or more longitudinal slots (like the slot f, shown in Figs. 2 and 3) to afford access to the interior of the cop-chamber for the purpose of threading the cop thread or yarn through the guide-tube or leader.

The shuttle may be adapted to contain a cop loosely mounted upon an axial pin like an ordinary cop skewer or spindle G, which spindle is preferably affixed permanently to the detachable end B, as shown in Figs. 2 and 10; or the detachable end B may be provided with an axial pin H for insertion in the head h of a bobbin upon which the cop has been Wound, and which, together with the cop Wound upon it, is introduced into the copchamber, as illustrated in Figs. 3 and S. In the latter case the head h of the bobbin may be provided with outwardly-projecting pins or lugs h', so placed as to bear against the ends of the tongues a a a when the end B is attached to the cylinder H, in which case, as will be seen, the base of the bobbin Will be held against the diaphragm Il', which is secured to the detachable head and from the center of which the bobbin-pin H progects. In the latter case the stem h2 of the bobbin performs the function of the cop skewer or spindle G in respect of its extensive projection into the cop-chamber; but the centralizing of the cop in the cop-chamber is ordinarily due to the axial pin H, the alignment of which corresponds with the axial alignment of the spindle Gr.

It is preferred to provide the cylindrical shell A and the adjacent portions of the ends A and B either with longitudinal corrugations-such, for instance, as those illustrated in cross-section in Figs. 12 and 13-or to fasten upon the exterior of the shuttle thev longitudinal ribs i, (indicated in Figs. 4, 5, and 6,) in order to. secure clearance for the free play of the cop-thread outside the shuttle when the shuttle is in the shuttle-box, wherein it is clamped by the ordinary protector or spring. As will be seen, the ribs or corrugations are so arranged that the shuttle may be conveniently used either in a round or a square shuttle-box. The ribs or corrugatlons also serve to strengthen the Wall of the shuttle and to form bearing-lines of the shuttle upon the warp-threads during the passage of the shuttle through the shedding.

The shuttle may be run. in a direction coincident With its longitudinal axis in any position which may be desired. Thus the cop thread or yarn may be made to pass from the top, bottom, or either side of the shuttle with# IOO out any alteration other than the placing of the shuttle in the shuttle-box in the position desired.

The extremities of the shuttle may have ordinary points J, as illustrated in Fig. 8, or the shuttle may be provided Withsolid ends J as illustrated in Fig. 10, or the interior of the ends may be filled with an elastic or semi-elastic substance j to prevent the exterior from being forced out of shape, as illustrated in Fig. 1l. In the latter cases the ordinary tubular -aperture F in the solid or iilled head takes the place of and is the equivalent ofthe guide-tube F as the leader for guiding the cop thread or yarn outside the shuttle.

/Vhat is claimed as the invention isl.
